In the process of Chen Ya propping the boat forward, through Juzuo's speech, the students in the live broadcast room knew the role of phased radar, and also knew that there was a radar matrix without dead ends around the dam.

And then, without involving performance parameters, this old expert, as much as possible for young people, talked about national defense technology.

"Ah...... Next, let's learn about the 30 close-in defense gun, this defensive weapon, the main function of which is to intercept targets at close range, it has a 30 mm caliber launch tube, and the average rate of fire per minute is up to 000 rounds, ah...... It can be called the first in the world. ”

Once the chrysanthemum Zhang Shaozhong enters the state of lecturing, the old mistake is committed again! As he speaks, he will bring the word 'ah', and the netizens in the live broadcast room, although they think it is very funny, are also listening carefully.

At the same time, the news of Chrysanthemum's lecture is rapidly spreading on the Internet, and the popularity of the live broadcast room is rising wildly at the moment, and the barrage is also endless.

"Go back to ten years ago: haze anti-laser, kelp wrapped around submarines!

"Type 59 light, medium and heavy tank destroyers: members of the battle situation, come to report!"

"FT Killing: Battle Squad Member+, I like to listen to Chrysanthemum lectures!"

"Too lazy to become an immortal: team member +2, thank you to the anchor for letting Juza come!"

......

A large number of netizens have poured into the live broadcast room, making the popularity soar all the way, in addition, there are countless people discussing the topic of close defense artillery.

"Chess: 000 rounds per minute? Isn't that more than 0 rounds per second? This is awesome!"

"Cold-hearted casual wind: really fake? I don't believe it anyway! Unless you find a target position and hit a dozen!"

"The dazed on the journey: That's right! Since we can speak freely, then we can say whatever we want!"

"Call of Poison: Raise your hand if you support target shooting!"

"Peace and Auspiciousness: Raise Your Hand+"

"Raise Hands +999"

......

Give a yarn!

Chen Ya, who was holding a bamboo raft, immediately rolled his eyes when he saw the barrage, do you think you can shoot if you say that you can hit it? Don't bullets cost money? The most important thing is where there is a target position near here?

Do you want to hit me?

Chen Ya didn't want to be shot into a hornet's nest for a second, and at this moment, after Juzuo finished telling the knowledge of the close-in defense artillery, the drone in mid-air immediately turned the camera and pointed at the big green boxes on the mountain peaks.

"Ah...... Now let's talk about the ZTZ-99 main battle tank, which is the third-generation main battle tank of China's land battle ace, also known as the Type 99, its turret and hull are made of composite armor ......"

There are a lot of balabala, it may be that Juzao is old and a little verbose to talk about, but netizens don't mind, and Chen Ya, as a listener, does not forget to take the initiative to ask some questions to Juzao on behalf of netizens.

Like, what the hell is composite armor?

Kikuza replied with a smile:

"Composite armor is a small square on a tank, and those armor plates are composed of a variety of materials that can effectively resist armor-piercing shells. ”

Tanks, as the king of land warfare, are almost always mobile fortresses, and after wearing composite armor, they are simply strong and fierce!

And then, Kikuza began to talk about the 730 missile defense system, which roughly means those honeycomb-like dense small missiles, which are used to intercept targets at medium and long distances, and are also defensive weapons.

The characteristic is that after approaching the target, the missile will suddenly accelerate and destroy the target in an instant before it can evade it.

When talking about this, Kikuza smiled and said:

"This technology was shared in the nineties by our good friend, Bar Kistan. ”

As soon as these words came out, the netizens in the live broadcast room instantly became energetic!

"Heavenly Court Soldier: Hahaha, thank you Brother Ba Tie!"

"Tiandu Wujun: There's nothing wrong! These decades of friendship have not been in vain!"

"Our name is Hs: Brother Ya, let's go to Ba Tie to survive in the future!"

"Yan Yu @ Our name is Hs: Crazy, aren't you?

"Ten Thousand Years Voldemort: I'm afraid of hair! Our brother Ya is the king of chicken eaters!"

......

Seeing the barrage, Chen Ya smiled, but at this moment, a roaring sound came from high in the sky.

Woooooo

As if the air was being rubbed, Chen Ya couldn't help but raise his head, and the drone in mid-air also turned the camera.

However, the golden clouds in the sky broke through, and a silver-gray fighter plane suddenly flew out, with its diamond-shaped fuselage and anti-duck wings, giving people a strong sense of picture.

In an instant, the netizens in the live broadcast room collectively opened their eyes wide, and the atmosphere reached a climax in an instant!

Seeing this, Zhang Shaozhong said with a smile:

"Ah, this...... I don't need to introduce it again, do I?"

This is the J-20!

Chen Ya's eyes also widened, this is Huaxia's latest fifth-generation stealth fighter, with supersonic cruise capabilities, and it can also engage in air combat.

The appearance of the J-20 shocked the audience!

But the more exciting is still to come, but I saw the J-20 in the sky, quickly dived downward, like lightning, and then suddenly went up, and the fuselage was instantly erected.

Then, the fighter plane flew vertically in the air, like a cobra raising its head in the sky, which was simply handsome!

Seeing this, Juza said with a smile:

"Ah, this is the Pugachev Cobra maneuver. ”

Awesome!

Chen Ya also had to admire in his heart, and the J-20 shook its wings from side to side after making a maneuver, and Juza said with a smile:

"The pilot of the J-20 is greeting everyone. ”

Hearing this, the netizens in the live broadcast room were immediately overjoyed! And when Chen Ya saw this, he couldn't help but smile and wave his hand, but unexpectedly, after shaking its wings a few times, the J-20 quickly swooped down towards the Yangtze River.

"What is this for?"

Chen Ya was a little confused, but the chicken eaters in the live broadcast room were instantly excited!

"Yuan Zzz: Brother Ya, can't you see it? This is the rhythm of the airdrop!"

"Bookworm Egg: Carman! Streamer hurry up and get ready to grab the airdrop!"

"Summoning Snow in the Cold ZZ: The airdrop smashed his face, Brother Ya's luck is here!"

"Flood Desolation Grim Reaper gg: What are you blind about? This is a J-20, not a transport plane!"

......

At this moment, Chen Ya stared at the swooping fighter plane, and did not pay attention to the barrage, but when he found that the J-20 suddenly accelerated, and a white cloud of air appeared on the fuselage, his face changed in an instant.

"Wori!"

Chen Ya scolded, immediately picked up the leather otter, and quickly jumped into the river.

Whoa!~

Immediately afterwards, the J-20 swooped into the valley, and flew over in the blink of an eye at a height of two hundred meters from the surface of the Yangtze River, with a sonic boom, like a bolt of lightning.

Rumble!!!!

The river below was stirred by the air waves, but Chen Ya in the water felt a burst of tinnitus, and the leather otter in his arms was even more fried, almost scared out of Xiang!

Even the drone in mid-air swayed from side to side under the influence of air waves, which made Chen Ya cry and laugh:

"Scare me, isn't it fun?

Obviously, this sentence was said to the pilot of the J-20, but the netizens in the live broadcast room laughed one after another! Many people know that the fighter pilots are very characterful, and the same is true of the one in the sky, who will actually fly down to scare the anchor.

And Juzao also laughed out loud, and at the same time took this opportunity to popularize science for netizens.

"A circle of white fog on the fuselage of the J-20 is a sound barrier phenomenon formed when the aircraft breaks through the speed of sound, this kind of ......"

Hearing Juzao's speech, Chen Ya was also convinced, and could only say with a smile:

"!

What else could he say? In addition to, it was still! Although some of his previous pranks frightened him, he was still very happy to see the state's high-precision weapons with his own eyes.

The netizens in the live broadcast room were extremely excited, and they sent out a barrage one after another, discussing whether the pilot of the J-20 would be a girl?

It seems like...... Only girls are so skinny, right?

Chen Ya climbed onto the bamboo raft again, fortunately the nylon rope was very strong, otherwise it would have fallen apart a long time ago, and then picked up the pole and continued to hurry.

At this moment, he had reached the third bend, only three kilometers away from the Three Gorges Dam, and although he could not see the super dam due to the obscuration of the mountain peaks, he could hear the rumbling sound of water.

It is clear that the Three Gorges Dam is opening its gates to release water.
